Changeset 1757eb594b in tspsg for docs/html/inherit__graph__1.png

+ Added Fractional accuracy (in decimail places) to settings.
+ Created defaults.h file. Moved all default defines there.

• Replaced all double types with qreal.
• Replaced all calls to trUtf8() with tr() as we use setCodecForTr() to set UTF-8 encoding as default and tr() is enough.
• Replaced all 2009 with 2010 in copyrights.
• Fixed an error when loading .zkt file with less than 5 cities.
